HUMANIN
What We've Seen in Practice, and What the Research Says
Humanin is one of the more remarkable molecules in this directory, and the reason is where it comes from. Most peptides are pieces of proteins your cells build from instructions in the nucleus. Humanin is different: it is written into the DNA of your mitochondria, the tiny power plants inside your cells, and it was the first such peptide ever found. That origin is not just trivia. It places humanin at the intersection of energy, aging, and cellular survival, which is exactly where the research has focused.
It was discovered in an unexpected place. Scientists studying the brains of people who had died with Alzheimer's disease found a small peptide that seemed to protect neurons from the damage the disease causes, and they named it humanin. Since then it has been studied for far more than the brain: for metabolism, for the heart, and for aging itself, where one of its most interesting features is simple. The amount of humanin your body carries falls as you get older, and people who carry more of it, or a particular longevity-linked version of it, tend to live longer.
We use humanin, and we will be candid about how. It is a quiet peptide, not a dramatic one, and it fits a specific role in a longevity plan rather than producing an effect you feel. That honesty is where
we will start.

What we've seen in practice
Humanin belongs to a small family of what are called mitochondrial peptides, made by the mitochondria themselves. Two others in that family are MOTS-c and SS-31. Where MOTS-c leans toward fitness and performance, humanin leans the other way, toward DNA repair and recovery, which is why Dr. Koniver thinks of it as a longevity peptide rather than a performance one.
Here is the honest part, and we lead with it because it shapes everything about how we use humanin: most people do not feel it. A few describe a smooth, clean sort of energy, but for the majority there is no obvious sensation, and we would rather tell you that plainly than imply otherwise. Dr. Koniver describes humanin as more of an insurance policy, a background peptide working at the level of cellular repair and resilience, not a peptide you take to feel different that afternoon. If you want something you notice, humanin is not it. If you want a quiet contributor to a longevity plan, it fits.
The way we use it reflects that. Humanin pairs naturally with NAD, another cornerstone of the longevity and mitochondrial work we do, and we most often provide it as a combination, NAD together with humanin, as a convenient at-home injection for our patients. For some people we extend that to a three-part combination of NAD, humanin, and SS-31, another mitochondrial peptide. Mixing these mitochondrial tools with NAD has worked well in our hands, and humanin earns its place in that stack as the DNA-repair-and-longevity component.
One practical note. Humanin remains available to be compounded, which is not true of every peptide in this directory. So unlike some of the peptides we have written about losing, humanin is one we still reach for today.
The research behind these observations, including where it is strong and where it stops, follows below.

A quiet longevity and DNA-repair peptide we still use, usually combined with NAD; most people do not feel a distinct effect. See what we've seen in practice above
The 24-amino-acid sequence. Because it is encoded in the mitochondria, humanin is made in a different part of the cell from most peptides.
Where HUMANIN comes from
Your cells carry two sets of DNA. Most of it sits in the nucleus, but your mitochondria keep their own small, separate genome, a leftover from their ancient origins as independent organisms. In 2001, researchers looking at surviving brain cells from Alzheimer's patients traced a protective peptide back to that mitochondrial genome, specifically to a region normally thought of as doing something else entirely. That peptide was humanin, and it was the first evidence that the mitochondria write their own signaling molecules, not just the machinery of energy production.
The discovery reframed how scientists think about mitochondria. Rather than being simple batteries, they turned out to send messages to the rest of the cell and the body, and humanin was the first of these messages to be identified. What makes it compelling for aging research is the pattern that emerged next: humanin levels are high in the young and fall with age, and both long-lived animals and long-lived people tend to carry more of it. That has made humanin a favorite subject in longevity science, and it is the frame most of the research below sits inside.
How HUMANIN works

At its core, humanin protects cells from dying under stress. It binds and neutralizes the proteins that trigger the cell-death cascade, which is how it protected neurons in the studies that led to its discovery. That anti-cell-death activity underlies most of its other effects. [1, 4]

Humanin acts on a receptor complex on the cell surface that switches on pro-survival signaling inside the cell, and it engages a second receptor system involved in inflammation. Through these it protects tissue, calms inflammatory signaling, and supports cells under stress. [3, 4]

As a mitochondrial peptide, humanin helps protect mitochondrial function, and in animal and cell studies it improves insulin sensitivity and protects the insulin-producing cells of the pancreas. These are the metabolic threads of its longevity story. [1]
A coherent preclinical record and real human association data, still lacking a treatment trial [1,2]
What the research shows
Here is the whole picture, told plainly. Humanin has an unusually coherent body of research for a peptide, and it is still missing the one kind of study that would make it a treatment.
From the research: the preclinical case is strong and consistent. Across cells and animals, humanin protects neurons from Alzheimer's-related damage, improves measures of metabolic health, protects the heart in injury models, and, in animals, is tied to longer, healthier lifespans. The human side is genuine but of a different kind: rather than treatment trials, it is association data. Researchers have shown that humanin levels decline with age, track with metabolic and disease markers, and that a specific longevity-linked variant of humanin is more common in people who live longer and appears to resist Alzheimer's-related brain changes. [1, 2, 4]
What does not yet exist is a human trial that gives people humanin and measures whether it changes an outcome. So the honest description of humanin is "a naturally occurring peptide with a strong preclinical record and real human association data, still lacking a human treatment trial." We hold it to that standard, which is part of why we describe its role modestly.

The evidence, area by area
The teal chip is real human evidence, but observational (levels and variants), not a treatment trial.
Humanin has a reassuring safety picture as far as it goes. It is a peptide the body makes on its own, it has been well tolerated across preclinical studies, and in our own use it has been well tolerated too, with the honest caveat that its effects are subtle enough that there is little for a patient to react to in the first place.
Two cautions follow from its biology and deserve stating. First, because humanin is fundamentally a cell-survival signal, there is a theoretical reason for caution in anyone with an active or prior cancer, since you do not want to send a broad survival signal in that setting; that is a decision to make carefully with your physician. Second, because humanin can improve insulin sensitivity, it can lower blood sugar, so anyone with diabetes or on glucose-lowering medication should be monitored. Pregnancy and breastfeeding are exclusions where safety data is lacking. And as with any compounded peptide, quality matters: humanin should come through a legitimate pharmacy, not an unregulated research-chemical supplier of unknown purity.

HUMANIN, answered plainly
It is the first known mitochondrial-derived peptide: a 24-amino-acid peptide written into the DNA of your mitochondria rather than the cell nucleus. It acts as a cell-survival signal and has been studied for neuroprotection, metabolic health, and longevity.
Honestly, probably not much. A few people describe a smooth, clean energy, but most feel no distinct effect. We use humanin as a background longevity and DNA-repair peptide, an insurance-policy kind of tool, not something you take to feel different that day.
Almost always with NAD. We most often provide it as an at-home NAD-plus-humanin combination, and for some people as a three-part NAD, humanin, and SS-31 combination. It is the DNA-repair-and-longevity member of that mitochondrial stack.
It has been well tolerated in research and in our practice, and it occurs naturally in the body. The main cautions are a theoretical one around active or prior cancer, because it is a survival signal, and blood-sugar monitoring for anyone with diabetes, since it can improve insulin sensitivity. Product quality matters, so it should come through a legitimate pharmacy.
It is not specifically listed by WADA, but that list changes annually and its sport status is not clearly defined, so any competitor should verify before use. The regulatory section above has the detail.[6]
